Imagine how awesome it would have been to have an amazing viral campaign along the lines of TDK... like where puzzles were revealed which showed pictures of Krypton, or just faint glimpse like shots of Kal-El's ship

All sorts of mystery viral puzzles could be done - like a riddle or puzzle that eventually leads to a reveal of characters.

Also, little blogs or even tiny TV spots or even huge spreads in all sorts of magazines or get the word out there that the action in this film is colossal, this is a giant heavy action adventure superhero film that will show a Superman we have never ever seen before.
